Biotin and lab tests: Beauty supplement poses risks for pregnant women | Your Pregnancy Matters

Biotin, also known as vitamin B7, is found in many beauty supplements that are marketed as hair, skin, and nail enhancers. But biotin – also known as vitamin B7 – can cause serious errors in medical test results.

In the past two decades, the percentage of adults taking biotin supplements has significantly increased. In 1999, just 0.1% of all adults took 1 mg/day of biotin. By 2016, consumer totals rose to 2.8%. Women tend to take even more biotin – one in 20 (4.7%) reported taking the supplement in a 2020 study.

In 2019, the U.S. Food and Drug Administration (FDA) issued an updated advisory about interference between biotin supplementation and common blood tests. High levels of biotin in a patient’s blood or urine samples can cause significantly incorrect lab test results. This can lead to incorrect diagnoses and improper treatment of conditions, such as ectopic pregnancy, miscarriage, or heart and thyroid issues.

How much biotin is safe?

The Institutes of Medicine recommends a daily biotin allowance of 30 mcg (0.03 mg) for most adults. Unfortunately, supplement labeling is not strictly regulated, and your product may include more B7 than you might think.

Many products offer mega-doses, with some touting 10,000 mcg (10 mg) or higher. That’s more than 300 times the recommended allowance. If you’re also taking a general multivitamin, you may be getting an even higher daily dose.

How biotin interferes with lab testing

Some lab assays use biotin during the testing process. Increased biotin from a patient’s blood sample can bond to specific proteins during the testing process, leading to inaccurately high or low test results.

3 lab tests women should know about (and how biotin affects them)

1) b human chorionic gonadotropin (hCG): That’s right, the pregnancy hormone. Having a high level of hCG can be an early indicator of pregnancy. We also test for hCG levels to determine whether a patient might be experiencing an ectopic pregnancy or miscarriage.

Biotin supplements can cause false low levels in blood tests. That means you may be pregnant or experiencing an ectopic pregnancy or miscarriage and might not know it. In urine tests, high levels of biotin may prevent the control line on your home pregnancy test from appearing, yielding invalid results.

2) Thyroid stimulating hormone (TSH): Thyroid dysfunction is common – 1 in 8 women has a thyroid problem. To diagnose new thyroid disease or assess an existing condition, we measure TSH levels. Too high and you may have hypothyroidism. Too low, you may have hyperthyroidism. Taking too much biotin can cause false low levels of TSH, which may prompt unnecessary treatment that can lead to actual thyroid issues.

3) Troponin: Troponins are proteins found in muscles, including the heart. Elevations of certain troponins aid in the diagnosis of heart attacks. However, biotin supplementation can lead to falsely low troponin levels, which can delay diagnosis. This is especially alarming for female patients, since heart attack symptoms in women may be more subtle.

Missed heart attack diagnoses carry the risk of potentially serious clinical implications. The FDA has received a report that one patient taking high levels of biotin died following falsely low troponin test results.

Lab tests that involve the protein ferritin or these hormones listed here can also be skewed by biotin supplementation:

  • Cortisol
  • Estrogen
  • Progesterone
  • Testosterone

Product name: 21st Century, Biotin, 10,000 mcg, 120 Tablets
Quantity: 120 Count, 0.07 kg, 9.7 x 6.1 x 4.6 cm
Categories: 21st Century, Supplements, Hair, Skin, Nails, Biotin, Gluten Free, Laboratory Tested

Hair, Skin and Nails Support, Vitamin Supplement, Gluten Free, Guaranteed Quality – Laboratory Tested, Biotin is part of the B-complex vitamins that provides support for hair, skin, and nail health. It is an essential nutrient for normal metabolism of carbohydrates, proteins and fats.

An over- or underactive thyroid may cause hair loss and dry strands. However, maintaining an optimal protein ratio in our daily diet is an important component when it comes to repairing and improving our hair, skin and nails. My hair is in lovely condition, but that is, i think mainly due to how i have changed my treatment of it. Tati westbrook, the beauty guru, faced backlash about her supplement line from skeptical fans who challenged her on pretty much every single claim and ingredient. With collagen made from cow skin, coconut water powder, and earthy matcha, this mix-in beauty supplement powder provides your body with all of the amino acids it takes to grow glossy, strong tresses and smooth, plumped skin. I had a manicure 2 weeks ago where as my nails were pretty much short. The study concluded that biotin might not be effective for people without medical conditions causing hair and nail breakage. Yet surprisingly, within two weeks of faithfully taking the capsules each day, i realized my nails had drastically changed. But remember: If you are eating a healthy diet that includes meats, seeds, nuts, and vegetables, you are most likely reaching this intake already, and the biotin side effects might not be worth it. While it’s supposed to strengthen hair, skin and nails, it could cause a skin rash if you are taking large amounts of biotin.

21st Century, Biotin, 10,000 mcg, 120 Tablets: Biotin, Nails, Skin, Hair, Supplements

Tell me: Does biotin work for hair growth? Lol when i have asked my friend on how she kept her hair great, she recommended biotin and ever since then my hair has been staying on my head haha and becomming longer. My hair was about to the middle of my back and it is now down to my waste, and it is thicker, shinier and healthier than a woman half my age’s. Collagen, which was first popularized in asia as an ingestible and comes with claims that it increases skin elasticity, is also popular. But this new iteration of shiny, celebrity-endorsed supplements is smack in the middle of the venn diagram of three huge and utterly modern obsessions: Wellness, skin care, and instagram, helping to drive their popularity like never before. One shopper said those annoying baby hairs along the hairline and those tiny, unruly strands were repaired after taking these for some time. If your toenails are yellowish for no good reason, like fungus, supplements might be the answer, according to new york podiatrist, bruce pinker, dpm, pc.

Then i talked to my vitamin expert at my health food store and she said many people were having results from 10,000mcg of biotin direct. Women say it helps bring fullness back to thinning hair while also restoring shine and speeding up growth. Whether you use nutraceuticals for medical, nutritional or beauty purposes, it is always a smart idea to do a little research about what you are putting in your body. If you choose to take supplements, can you ensure that they are safe? I mean, the supplement has 10 solid nutrient forms (The ones just mentioned). Two crazy-delicious gummies a day can help improve the look of skin, nails, by dosing your system with protein metabolizing biotin, keratin, and vitamins c and e. Westbrook is not the first social media star to shill beauty supplements. I am 41, always had long hair although i’d cut it off from time to time, but it has always been thick. I have been experiencing hair loss over the slightest of tugs, will this reduce the amount of hair i lose?

My nails are super strong, my hair has grown and people are always making remarks about my skin, and i do not put anything on my skin, just take the vitamins. And hence, making the supplement overall quite a poor attempt at living up to being a multivitamin. It should resolve itself if you lower the amount of biotin you are taking or stop taking the supplement altogether. For dietary supplementation i started taking these nature’s bounty hair, skin and nails two weeks ago. I have very weak, peeling nails and have tried supplements and many base coat strengtheners and nothing has worked until this. My nails grew slowly and would split, have been taking the gummies for several years with great results. Is it really that you want only great hair, nails, and skin, or is it rather that you want proper overall health with the addition of improved characteristics for your hair, nails, and skin? Her rabid fan base tunes in for her beauty product reviews, hauls, and tutorials. However, they are pretty characteristic and reminiscent of a mediocre nutritional supplement. Since the rash continued for days after i stopped taking the supplement i tried it again thinking it could not have been it. We navigated reviews and sifted through the noise to come up with the best supplements that are pretty much miracle-gro for your hair and nails. In reality, supplements have been proven to work, but only for people with health concerns that interfere with their ability to absorb nutrients.

I recommend it to my patients who have any concerns with thinning hair or brittle nails. I can honestly say never in my life has my skin, nails or hair looked this great. First let me provide you with a little background on how the body keeps our hair, skin and nails healthy. I never had a supplement do this well in just a short period of time. A supplement with keratin, biotin, collagen peptides, hyaluronic acid, all the alphabetic vitamins, or any combination of the above can help your hair grow back longer and stronger in as little as a few weeks. It contains ingredients like biotin, kelp, saw palmetto, horsetail, ashwagandha, and ginseng. My hair grows so fast, and my nails, which are usually pathetic and weak, can last weeks without breaking or peeling. Everyone wants luxurious hair, glowing skin and strong nails, all of which depend on an adequate intake of nutrients. I was taking a lower dose of biotin, something in a hair, nails and skin vitamin. But the increasing popularity is most obvious when supplements are broken out as a sector of the beauty industry, where they previously were barely a blip. Most reviewers said this product allowed them to skip the dermatologist and stopped their hair from falling out.

21st Century Biotin

For dietary supplementation i have been taking these vitamins and had zero problems except a stomach ache but that was my own fault because the directions clearly state take with a meal. Together, the ingredients work to firm and increase elasticity in your skin, fight dullness and uneven texture, and even fill in fine lines and wrinkles over time. One reviewer wrote, it has taken 30 days, but well worth the wait, as i am beginning to see hair growth and much more volume on my crown. I continued to use them after getting sick repeatedly because i really wanted my nails to get stronger and for my hair to grow. I would recommend to every woman to add biotin to her diet! It’s often included as one of the ingredients in beauty supplements, but some consumers opt to take it alone. We all know that beauty is not simply skin deep, but the idea could not be more relevant thanks to a new breed of supplements designed to nourish your skin, hair and nails from the inside out.

What i am trying to get at is that the exact same is extremely likely to be said about the supplement of this review. Instead, at the end of february she unveiled a line of barbie-pink supplement capsules called halo beauty, which claim to do everything from prevent premature hair graying to firming skin and reducing fine lines. And without it, the supposed improvements to hair, skin, and nails will be short-lived and may eventually crumble. My hair has grown an incredible amount so quickly. My hair and nails have been growing like wild weeds and my skin is looking fabulous! For 4 days, i have been taking this supplement, and the itchy bumps kept increasing all over my arms. Philip kingsley, one of the original hair health brands, crafted this supplement (Full of b vitamins, selenium, and vitamin d) to mimic the nutritional recommendations they make at their hair health clinics in new york and london. It contains just the right balance of nutrients to help support lustrous hair, strong nails and vibrant skin. Whereas horsetail will boost collagen production, thus, strengthening hair, nails, bones, and teeth. I wish i had read reviews before purchasing the gummies, i am currently covered in hives and a crazy skin rash, on my torso region.

For dietary supplementation do not take these! My hair was also significantly more lustrous, so that even my husband took notice. A pharmacist confirmed for me that the bottle i had was actually getting me to consume more than 8,000 times the daily recommended amount of biotin (The bottle lists one serving as 833 times the daily value). Caution: As with any dietary supplement, you should advise your healthcare professional of the use of this product. For dietary supplementation do not buy this product. When i ran out of gummies i decided to try nature’s bounty extra strength hair, skin, and nails pills. But for those with no clear deficiencies, experts say there is no good evidence that supplements can make a difference. My shin is glowing and i have noticed a real improvement in my skin around my eyes. For dietary supplementation i had been taking generic gummy supplements for hair, skin, and nails for 5 months and did notice a difference in my hair and nails. The impact on the skin has been so pleasing that i do not wear foundation makeup anymore. My hair was so luxuriant and grew at least 2 inches as i continued the challenge for 2 months. My nails seem a little stronger too since they are not breaking as easily.

As with any dietary supplement, consult your healthcare practitioner before using this product. But does that mean all supplements are a waste of your money?

21st Century, Biotin, 10,000 mcg, 120 Tablets Product Review

Feedback for those on whom biotin at a horse dosage of 10mg DOES NOT WORK! Very helpful to my nerves, but got a not very pleasant side.

CHEGOU PRODUCT COMPLIANCE ADVERTISEMENT. good. I will use it well. Very good product! I will share a secret O f f: A X L five 6 zero 8 write in numbers without *. Hair stopped rolling. Best of most brands. Hair Growing But Not On My Head. Excellent

I drank this biotin for 1.5 months, 1t / day in the morning, placed high hopes on him. As always, I write the background to make it clear what’s what. I’m 28, my hair falls from childhood / from school. There was everything: stress, constant tension, improper diet, folk remedies and trips to trichologists, which gave nothing. Well at least, that these miraculous “spycilists” have not hurt, I’m not so lucky with everyone. Now the situation is so deplorable that I finally began to actively restore them myself, relying on myself and the Internet. So, taking biotin gave me completely different results, which I expected: 1) Reduced blood sugar (along with chromium from craving for sweet) from 5.3 to 4.7. I know, because because of anemia I often give blood, checking other important indicators. And biotin is included in the complexes against diabetes.2) Affects the metabolism. Subjectively. I’ll also assign it here a little calmer.3) Nails became stronger, which left me completely indifferent, because I need hair! As a result, I came to the following conclusions about what to do, so that BIOTIN WORKED: 1) Strengthen the action of biotin with other vitamins. From the reviews I see with what only do not take biotin: spirulina, zinc, silicon, iodine, L-cysteine, omega etc. This individual scheme should be selected independently, to watch what the body lacks. To hand over biochemistry, for example. I will drink most of these elements gradually, strictly observing their compatibility and monitoring the reaction of the body, because in my body there is not enough of everything and a lot now, this situation was accumulating for a long time a snowball. From this smoothly follows 2) Choose a good complex of vitamins hair-nails. I myself look closely at the keratin from Neocell and Maxi-Hair from Country-Life. In the special complexes, this is already there, including the patchy dose of biotin.3) From the obvious, the duration of the course. I was 1.5 months old. I will drink this jar to the end, dividing into a couple of courses and combining with other vitamins for the hair. I continue to make masks and smear good whey d / hair. Another feature of biotin (it’s vitamin B3, H, PP) is that excesses are eliminated from the body, so they will not cause harm to the body. On my page you can find many interesting and useful reviews. You can go there by clicking my nickname TalaniaSilver from the top. And if you still read my review to the end and it was useful to you, do not be lazy to press YES, so that I see that someone is reading these letters. All good health and beautiful hair.

Very good price for a really working vitamin. Unfortunately, he didn’t get through the entire jar, but he achieved the desired effect, in parallel he was still drinking other additives. After a month of intake, there were somehow a lot of very thick acne that was not squeezed out at all. Now they have passed by. Now I drink them little by little. In a high dosage in combination with OTHER additives (lecithin, retinol, alpha lipoic acid, D3, b-12, b-1, b-6, magnesium, manganese, and DMAE), you can quietly restore MYELIN. Specifically, my herpes began more than 2 years, destroyed the nerve roots, and the spine. It got to the point that I could not work normally, there was a strong weakness in the limbs and I had to change the work convenient for me. After treating the main cause, I was able, thanks to biotin, to restore the functions of the extremities, in just 2 months. In recent years, biotin has been tested at high dosages of about (100,000 – 300,000 mcg) in patients with MS, and there really is a result. The main thing to find the cause! And the main cause of stress. Also noticed that the skin tone lined and the nails stopped exfoliating. Hair really grows faster. Can be in combination with burdock oil and red pepper to germinate them in the right place. If you like my review, please click: YES :. I wish you all good!

arrived as the announcement, I will make use in the next days.

good. I will use it well.

Very good product! I will share a secret O f f: A X L five 6 zero 8 write in numbers without

Terribly hair climbed. I didn’t know what to do with it. Shampoos, masks did not help. I heard that biotin is pricked into the scalp like vitamins, and thereby strengthen and stimulate the bulbs. But for me it is too radical. I decided to drink. And so, not having finished the jar, I forgot about this my problem. Miracle! I’ll take it again. For prevention I will drink in the winter. Moreover, this is just as good for the whole organism as a whole.

One of the most effective on the market, and with such a ratio with the price, it’s completely ideal. But, it is extremely important not to take it as an independent vitamin supplement, only together with magnesium and omega3.

Despite its small size, the pill makes itself felt. Hair stopped falling out, nails began to grow, the main thing is to drink regularly, and not when you remember.

I bought after reading praise. A month later, I discovered that the hair was growing but not where it was needed, even the cosmetologist said that the drug clearly had a side effect on the endocrine of hair, but it was not upset on the head.

What is biotin? It is a vitamin B7 enzyme, which helps to increase red blood cells in the body, as it helps the growth of cells in the body, and it works to increase the amino acids in the body, which helps blood flow to the hair follicles, along with the blood flow to the skin tissues in The body, the body produces natural biotin in the blood by eating foods that contain vitamin B7 and vitamin E. The biotin is used in many synthetic compounds interested in hair and skin beauty.

Is it gluten free?
Hello, Does this contain any animal gelatin, especially pork gelatin? please answer

21st Century products are manufactured in US. I’ve been using them for years and, where Drs. can test for results, they have been successful. The biotin itself stopped my hair loss and improved texture and shine. You can check the label for FDA approval as well as I or you can contact them directly on their website.
Hi, it doesn’t mention it on the packet that I can see so I guess it’s not vegetarian I normally check before purchase must of been in a rush and didn’t notice this time. Thanks
Hi. As it helps with all hair growth (I have found this to be so), I imagine it definitely would. 🙂
i downloaded Foodpharmacy Blog application it’s more easy to order. if you buy things arround 68$the shipping fees become less approximately (8-15$) if you buy more than 68$you must pay taxes. you can also use my code it gives you 10% discount (A-T-T-8-4-4-5) without put dashes –

It is 10000 not 10 there are using a comma (, ) which is used for thousands separator and it is not a dot (. ) which is used as a decimal separator
Calcium is written/ present in this bottle of biotin. There’s a difference of opinion of daily value percentage of biotin to be 30mcg or 300mcg. Regardless of brand, results are guaranteed with 10, 000mcg equal to 10mg biotin. Remember to drink lots of water daily though to avoid swelling of body.
in the ingredient, they didn’t mention Gluten free. I wouldn’t take it if I am looking for Gluten free. hope this helps.

Spring Valley Biotin 10,000 mcg Reviews – Viewpoints.com

I absolutely love this stuff! It has helped me out in the hair department wicked quick like. These little soft gels are like hairicale grow. I personally use the 10,000mcg, while it says its a once a day pill, you cannot overdose on biotin…So doubling up for the first 2 weeks is a great way to jump start the substance. Once in the morning and once at night, always with food and a decent amount of water. This will force your system to take as much of the vitamin as possible before flushing the rest out in your urine.
Now, I know while all of this sounds great its hard to just go off of a bunch of words. I am going to give you some date length stats…
My Sister and Myself- Started Sept. 23
SISTER -1st check on Oct.1 – 1/2IN GROWTH / MYSELF – 1st check on Sept. 30- 3/4IN GROWTH
SISTER – 2nd check on Oct. 5 / MYSELF – 2nd check on Oct 5 (early for review)
we both checked this morning and she is at a full inch of growth, while I am pushing by her at almost a full 2 inches. I wish I could add picture for you ladies.
these pills are fantastic, they have cleared up my sisters skin and have helped her hair to become far more calm. My hair is keeping its oils longer and helping my frizz top to be a bit more manageable(spanish girl curls are always a beast ALWAYS).
All in all even while taking my other supplements I have noticed an amazing change in the last 2 weeks of taking the biotin(doubled for first 14 days.)
-my step mom is a hair dresser she is who first recommended biotin and the doubling method so if you are curious or thinking about biotin ask your hair dresser(i know women are close to their hair dressers), they will be able to give you all the info you’ll need to go buy some same day!
good growth luck everyone.


Biotin Hair Supplements – Side Effects, Dosage, Safety

If you’ve hung out in your drugstore’s vitamin aisle before, you’ve probably bumped into this cool kid on the block: biotin. Sellers of this beauty supplement make some pretty big promises. People claim it can give you hard-ass nails, hair that’s sleek AF, and flawless skin that could only otherwise be achieved by an Insta filter.

It’s cheap and easy to access over the counter (plus celebs like Kylie Jenner have posted #ads for biotin for hair on IG), so it comes as no surprise that women are popping biotin in droves.

But is this supplement really the godsend it claims to be? And are there any biotin side effects of biotin you should know about? Your guide, ahead.

What is biotin, anyway?

Biotin (a.k.a. vitamin B7 or H) is a B-complex vitamin that’s found in many foods, including eggs, milk, nuts, and grains, says Shaemah Khan, DO, diplomate of the American Osteopathic Board of Family Physicians and clinical associate of family medicine at University of Chicago Medicine. “One of the effects of biotin is that it helps turn the carbohydrates, fats, and proteins in the food you eat into the energy you need.

Because it’s water-soluble (meaning it dissolves in water), excess biotin isn’t stored in your body; it actually just flushes right out of you when you pee. But if you follow a healthy, balanced diet, it’s likely you already get all the biotin you could possibly need, anyway. (More on recommended biotin levels later.)

But wait, is it possible to have a biotin deficiency?

Although it’s uncommon, it is possible to be deficient in biotin, says Rajani Katta, MD, a dermatologist in Houston and author of Glow: The Dermatologist’s Guide to a Whole Foods Younger Skin Diet. There are some genetic conditions that can cause you to have low biotin levels, like biotindase deficiency disorder, and this can lead to hair loss, red flaky rashes on the skin, and brittle nails. Other factors that might lead to lower levels of biotin are smoking, excessive alcohol intake and pregnancy. People who take certain anti-epileptic medications may also develop a biotin deficiency.

You’re also more likely to develop a biotin deficiency if you have a condition that impacts your digestive tract, like inflammatory bowel disease or small intestinal bacterial overgrowth. That’s because biotin is naturally produced by certain gut bacteria in the intestines, so any condition that throws off the microbes in there can impact the effective production of the vitamin, says Dr. Katta.

Still, “our bodies require only a very small amount of biotin, which is easily achieved if you’re eating a relatively normal American diet,” says Kimbre Zahn, MD, family medicine physician at Indiana University Health.

What are the heath benefits of taking biotin?

Aside from being touted as a magic remedy for thinning hair, brittle nails, and dry, itchy skin, biotin supplements can sometimes be prescribed by doctors for other reasons too, like easing disabilities brought on by multiple sclerosis, alleviating diabetes and diabetes-related nerve damage, or encouraging baby growth and development during pregnancy, according to the National Library of Medicine.

Most of the touted beauty benefits, like stronger nails, are anecdotal though. “There have been a few very small studies indicating that taking biotin can lead to an improvement in brittle nails, but it’s important to note that we do not know these patients’ baseline biotin status, and the studies did not include a placebo group,” says Dr. Katta.

Overall, there’s very little evidence that taking biotin can help people in the absence of a deficiency. In other words, if you don’t have any signs of being deficient in biotin (which, again, is rare), then taking extra hasn’t been proven to have benefits, says Dr. Katta.

Tell me: Does biotin work for hair growth?

Don’t get toooo excited. A few studies point to biotin as an effective supplement for hair growth, but the cold, hard truth is that there isn’t much scientific proof to show just how effective it really is at treating any of these health conditions—or whether there are long-term benefits to the dietary supplement.

“While there are some preliminary studies that may suggest a benefit [to taking biotin supplements], overall there is a lack of evidence to support these claims,” says Dr. Zahn.

Dr. Katta also notes that there’s no research on how biotin affects women of color’s hair and bodies, so there’s no saying if it would result in any improvements for natural hair.

“Unless you are deficient, I don’t recommend taking extra biotin since there is limited evidence that it results in hair and nail growth,” she says.

How can I get more biotin from my diet?

Dermatologists recommend eating more of these foods if you want to up your biotin intake without taking a supplement.

  • Egg yolks
  • Nuts
  • Seeds
  • Sweet potatoes
  • Salmon
  • Lean meats, or organ meats such as liver

    Does biotin have side effects?

    Truth is, you’re most likely never going to hear about someone ODing on biotin. It almost never happens. “Side effects from having a high dose or overdose of biotin are rare,” says Dr. Khan. “Because it is so easily excreted in urine and feces, the body can simply get rid of any excess.”

    However, hair, skin, and nails supplements do come with one warning: Even in small amounts of biotin, one of the side effects of biotin is that it can sometimes totally screw with your lab test results. This is especially true if you’re testing for issues with your thyroid or hormone levels, cardiac troponin levels (used to diagnose heart attacks), or vitamin D levels. This could lead to bogus results and misdiagnosis, which could potentially be dangerous or lead you to worry or spend money on medical procedures or meds unnecessarily.

    “The U.S. Food & Drug Administration (FDA) further warns that the biotin effect on the monitoring of cardiac troponin has resulted in at least one death due to a falsely reported low results,” says Michelle Galant, MD, dermatologist at Stanford Health Care.

    If you do take biotin, keep this in mind the next time your doc orders a routine lab test. “It’s best to disclose to your doctor and dietitian which supplements you are taking to avoid misdiagnosing a medical condition,” says Sandra Arévalo, RDN, spokesperson for the Academy of Nutrition and Dietetics and the American Association for Diabetes Educators, and director of nutrition services outreach for the community pediatrics programs at Montefiore Hospital.

    There’s no hard evidence that says exactly how long biotin stays in your system after you take it, so your doctor might recommend you stop taking the supplement a few days before you head to the lab.

    Other potential biotin side effects? While it’s supposed to strengthen hair, skin and nails, it could cause a skin rash if you’re taking large amounts of biotin. See your doctor if you develop a rash after taking biotin or increasing your dose. It should resolve itself if you lower the amount of biotin you’re taking or stop taking the supplement altogether.

    “Some people have also reported digestive upset from extra biotin,” Dr. Katta says. “We also don’t understand exactly how large doses affect insulin function and blood sugar levels in different people, so that’s an area that definitely needs further research.” Again, before you start taking a supp, talk to your doc to make sure it won’t interfere with any meds you’re taking or any conditions you have.

    Should I even bother taking biotin?

    Honestly, probs not. Thanks to its lack of scientific backup and its reputation as a lab test saboteur, biotin isn’t generally recommended by most doctors. But if you still want to take it anyway, just make sure you’re buying a reputable brand (look for the “USP verified” on the label), and are aware of the side effects.

    In terms of how much biotin you need, the recommended “adequate intake” (AI) level for biotin is up to 30 micrograms (mcg) for women 19 years old and up, says Arévalo. “Pregnant women should consume 30 mcg; 35 if nursing,” Arévalo adds.

    But remember: If you are eating a healthy diet that includes meats, seeds, nuts, and vegetables, you are most likely reaching this intake already, and the biotin side effects might not be worth it. “If you are skipping certain foods or food groups, it will be good to talk to a registered dietitian to help you find which nutrients you might be deficient in, and whether you need to supplement or just eat more of other foods,” says Arévalo.

    Recently the consumption of biotin (vitamin B7, component of multivitamins and of hair and nail products, medication for Multiple Sclerosis) has increased and as result the following interfering patterns have been observed:
    increased FT4 and decreased TSH mimicking Graves disease or hyperthyroidism; 
    decreased PTH with increased vitamin D mimicking PTH suppression or vitamin D intoxication;
    increased cortisol with decreased ACTH mimicking hypercortisolism (1)

    Because some immunoassays will show falsely decreased (TSH, CA 125, prolactin, F-PSA, NT-PBNP) while others falsely increased values (T3, FT4, cortisol, estradiol, folate) some interference combinations can mimic certain disease states that will not match the clinical picture, and consultation with the laboratory is recommended. T-messages explaining the possible interference will be attached to the results that could be affected.

    Risk to Patient:
    Although present in literature these interferences are rare: the patients at the highest risk of misdiagnosis are 
    consumers of high dose of biotin (Multiple Sclerosis, or oncology patients 100,000 mcg/day)
    patients who take increased amounts of pure biotin or beauty products (5,000 to 10,000 mcg/tablet),
    patients who take biotin in an moderate amount but have kidney failure who having a delayed clearance of the vitamin.

    Biotin, vitamin B7 or vitamin H is a water-soluble vitamin eliminated through the kidney with a half-life between 8 and 24 hours, variable from person to person and increased with kidney failure. Because biotin deficiency is considered extremely rare, no RDI exists. Suggested biotin intake for adults ranges from 30 – 100 mcg per day. Standard multivitamins contain usually 30-50 mcg/tablet, amount will not interfere with our testing, while the beauty products and the MS medication might produce interference.

    We recommend asking the patient if he/she is taking treatment, multivitamins or beauty products containing biotin. 
    A 12 hour abstinence would ensure the clearance of biotin to a level that would not interfere with our results if the patient takes regular multivitamins or beauty supplements. 
    For patients taking doses exceeding 5,000 mcg/day (usually MS treatment) a longer period of abstinence as well as consultation with the laboratory is recommended.
    The laboratory is able to identify biotin or any other interferences, communication with the laboratory is recommended whenever the results are discrepant with the clinical picture.

    Clinical chemistry testing (electrolytes, glucose, creatinine, lipids, liver enzymes) based mainly on chemical and enzymatic reactions and immunoassays performed on ELISA platforms like lyme, measles, autoimmune assays, or urine pregnancy tests are not affected by biotin but can be    influenced by other interferences.


    Our immunoassays are very accurate and reliable but various interferences are possible and a complete list of medication, accurate clinical history as well as a good correlation between the clinical picture and the laboratory results is imperative for patient care. 
    The laboratory has methods to identify possible interferences and we are at your service to discuss and follow up on any results that do not have a good clinical explanation, as well as to listen to any questions or suggestions that you might have.

    Biotin, the Missing Link to Your Healthiest Hair.

    On the heal of our Annual Health Risk assessment I felt it was only natural to share the abundance of information I am learning about vitamins and supplementation. I want to touch on the major vitamins, their benefits, their risk, and what they do best. I am also going to talk about the alternative to taking vitamins. So to start this series off lets talk Biotin!

    We all have heard something about Biotin, be it good or bad.  Today I am going to give some facts on this incredible supplement:  the type of vitamin it is, the important role Biotin plays in your body, and the best time of day you should take it.

    Biotin is a water-soluble member of the B-vitamin family; it is also known as Vitamin B7 or Vitamin H . Usually, you can get enough biotin in your diet through foods such as oatmeal, egg yolks, soy products, organ meats, bananas, peanuts and brewer’s yeast. Biotin is critical to the formation of fatty acids and glucose and the metabolism of amino acids and carbohydrates. Taking Biotin may halt symptoms of Biotin deficiency.  Biotin deficiency is rare but can cause serious complications.

    Biotin deficiency symptoms:

    • hair loss
    • dry skin
    • brittle hair
    • fungal infections
    • seborrheic dermatitis /rashes
    • fatigue
    • anemia
    • nausea
    • appetite loss
    • conjunctivitis
    • depression
    • dandruff / psoriasis / eczema
    • loss of muscular reflexes

    Biotin deficiency is important to treat right away because it can cause severe problems if it is left untreated, such as:  changes in mental status, muscular pains, hyperesthesias (abnormal increase in stimuli) and parenthesia (sensation of tingling skin), lethargy, hallucinations, and numbness and tingling in extremities.

    Note:  You should always contact your physician about your symptoms before trying to self-treat or to determine if Biotin will benefit your particular condition.

    Benefits of Biotin:

    • healthy hair
    • decrease acne
    • strengthen brittle nails
    • diabetes – Supplementation of biotin can help improve and lower blood sugar levels.
    • helps with eczema
    • decrease hair loss
    • helps with mild depression
    • skin rash in infants (also known as seborrheic dermatitis)

    Since Biotin is a water-soluble member of the B-Vitamin family it is best to take Biotin with your first meal of the day. Vitamin B is known for an influx of energy so consuming Biotin before bed time could make for a restless night.

    What are the risks of taking biotin

    • Side effects. Biotin seems to be safe and well-tolerated, even at fairly high levels. The maximum safe dose of biotin is unknown.
    • Risks. If you have any medical conditions — or are pregnant or breastfeeding — check with a doctor before using biotin supplements. Don’t give biotin to a child unless a pediatrician recommends it.
    • Interactions. If you take any medicines regularly, talk to your doctor before you start using biotin supplements. Biotin might weaken the effect of some cholesterol medicines. Conversely, many drugs can lower biotin levels, including some antibiotics and medicines for acne. Some epilepsy medicines may decrease biotin absorption from food. A supplement, lipoic acid, may also increase the need for biotin. Eating raw egg whites on a regular basis can also lower biotin levels in the body.

    I originally started taking Biotin because I wanted to strengthen my hair and nails. While it is the most common vitamin added to hair and nail beauty products, this vitamin has proven to be so much more for me.  The older people get the harder it is for the body to absorb vitamins. This means that healthy supplementation is a good way to ensure that proper vitamin levels are maintained.

    Vitamin for normal growth and development. Maintaining sugar levels. Beauty of skin and hair.

    What is biotin for?

    According to recent data, biotin plays an important role in carbohydrate metabolism, interacting with the pancreatic hormone insulin. In addition, biotin is involved in the production of so-called glucokinase, a substance that “triggers” glucose metabolism.

    Glucokinase is produced in the liver, where biotin is stored.This is especially important for diabetics, who have low levels of glucokinase in the liver. Thanks to biotin supplements (5 to 15 milligrams per day), doctors are able to significantly improve glucose metabolism in diabetic patients.

    Biotin also plays a significant role in the synthesis of glycogen – carbohydrates accumulated in the liver and muscles, as well as in the assimilation of these reserves and in the so-called gluconeogenesis, during which 16 out of 22 amino acids are converted into glucose. This process is critical to maintaining stable blood sugar levels.Thus, biotin stabilizes blood sugar levels.

    It also assists in the absorption of protein and in metabolism is an important ally of other B vitamins such as folic and pantothenic acid and vitamin B12. In addition, it is involved in the breakdown of fatty acids and in the burning of fat.

    Since biotin contains sulfur, it can be called a beauty vitamin for skin, hair and nails. In other words: who wants to be beautiful and make a good impression on people should not ignore biotin.The fact is that the skin, hair and nails need sulfur, and someone has to deliver it there. Biotin has established itself as an ideal vehicle that always delivers its sulfur load exactly to its destination.

    Since biotin controls fat metabolism and is predominantly found in the cells of the skin and hair, it naturally influences the fat content of the skin.

    Since biotin optimizes the use of fatty acids in the body and makes the scalp less oily, it can improve the overall structure and appearance of the hair.Although claims to stimulate hair growth are not backed up by any published research, biotin supplementation of 5 to 15 mg per day certainly stops biotin deficiency-related hair loss in balding men. However, male pattern baldness, which is hormonal in nature, is another matter entirely.

    Another important task of biotin is to bind carbon dioxide to purines, which contain the hereditary information of our body. It is also required for the synthesis of hemoglobin, a pigment in red blood cells.

    Together with the addition of beneficial bacteria, biotin may be useful in the treatment of seborrheic dermatitis in newborns. Its effect is not as effective against the adult version of the disease. Adults require a more comprehensive approach that includes all the B-complex vitamins along with essential fatty acids and minerals such as zinc.

    Consequences of biotin deficiency

    Just like vitamin K, biotin produces beneficial intestinal microflora, but the question of the amount of vitamin we get from this source remains controversial: some researchers believe that in this way you can get enough vitamin to meet the needs of the body without additional nutrition or additional additives under normal conditions.When deficiency does occur, the patient is usually a newborn baby because there may not be enough beneficial bacteria in its gastrointestinal tract. A small risk of biotin deficiency may exist in people who live on intravenous feeding for a long time.

    Also, if you are undergoing long-term antibiotic treatment – this applies to both children and adults – biotin synthesis can be drastically reduced due to the death of beneficial intestinal bacteria, which makes additional intake necessary. The same is true for those who regularly consume alcohol or have to take anticonvulsants. If you are into “athletic” breakfasts or eat a lot of raw eggs, you need to take additional biotin (at least 500 mcg per day) on an empty stomach.

    Raw egg white contains a substance called avidin, an anti-vitamin called biotin. This substance binds biotin and prevents its absorption into the blood. When heated, denaturation (irreversible structural breakdown) of avidin in the egg white occurs, and therefore the cooked eggs do not interfere with the absorption of biotin.

    Biotin is essential for maintaining stable blood sugar levels. Too low sugar content (doctors call it hypoglycemia) has become a new mass disease, which is constantly or periodically present in every second of us.
    Our brain and nerve cells only eat glucose. Therefore, the blood sugar content must constantly remain at a certain level – 80-100 milligrams of glucose per 100 milliliters of blood. At 60 milligrams, we become nervous, irritable, tired. At 40 milligrams, we are tormented in the morning by the question of how to survive this day. At 30 milligrams, we are unable to cope with everyday tasks. The most trifling conflict, the one and only “no” can lead to a nervous breakdown.

    Due to the fact that women can accumulate only 300 grams of glucose in the body (men – 400 g), their reserves are depleted faster. Blood sugar decreases at a faster rate, and women become nervous or depressed more quickly and have more insomnia than men.

    For all of these reasons, care must be taken to ensure that biotin replenishment is adequate.

    Since biotin controls fat metabolism and is predominantly found in the cells of the skin and hair, it naturally influences the fat content of the skin. Where there is not enough vitamin, seborrhea occurs – a violation of the function of the sebaceous glands. Its consequences are, in particular, hair loss and dandruff. And due to the fact that this also causes a deficiency of sulfur, the skin becomes pale and the hair dull. The nails also become more brittle.

    Magnesium is needed to convert biotin to its active form, and if you are deficient in magnesium you may also be deficient in biotin.

    Help for doctors

    Biotin is a prostatic group of carboxylation enzymes (introduction of a carboxyl group into a compound). Therefore, it is necessary for the synthesis of higher fatty acids included in the structure of the lipid components of the cell, as well as oxalic-acetic acid, a product of carbohydrate metabolism.Therefore, biotin plays an important role in these types of metabolism. In addition, it is required for the synthesis of purines that are part of the structure of nucleic acids.

    Biotin has a beneficial effect on seborrheic dermatitis, fragility and stratification of hair, nails, growth and development disorders. Improves the functional state of the nervous system and gastrointestinal tract. There is evidence of the ability of biotin to lower blood sugar levels in type II diabetes. The need for biotin increases with long-term treatment with antibiotics, which suppress the intestinal microflora that produces biotin.

    With biotin deficiency, apathy, muscle weakness, drowsiness, loss of appetite, dermatitis (the skin becomes dry, flaky, becomes red) develop, over time, the papillae of the tongue atrophy, and the functions of the nervous system are disrupted.

    Each capsule contains 10,000 mcg of biotin (3333% of the daily dose).

    90,000 Biotin Maximum, Biotin, Natrol, 10,000 mcg, 100 Tablets

    Biotin is a vitamin sometimes referred to as vitamin H or B7.It is one of the eight B vitamins. Biotin is naturally found in many foods such as meat, sea fish, cooked egg yolks, milk, poultry, legumes, whole grains and brewer’s yeast. Sometimes, the biotin content of food decreases when food is cooked or frozen. The best way to prepare biotin-rich foods is to steam them. Biotin, as a coenzyme, is involved in energy production. It is one of the agents that converts food into energy by converting fats and carbohydrates to glucose and breaking down proteins into amino acids.Biotin levels are inversely related to sugar levels; high biotin levels lower blood sugar levels and vice versa. Symptoms such as hair loss, skin irritation, fungus or eczema are common with biotin deficiency.

    Biotin promotes the growth of nails and hair.

    Biotin deficiency

    Biotin deficiency is rare in adults as it is readily available in many foods. However, the consumption of typically packaged foods can result in the loss of biotin along with many other nutrients.

    In infants, seborrheic dermatitis is one of the conditions that can be caused by a biotin deficiency. It is characterized by dry, scaly scalp.

    Lack of biotin is associated with depression. Other symptoms of biotin deficiency include anemia, high blood sugar, inflammation of the skin and mucous membranes, insomnia, muscle pain, loss of appetite, nausea, and sores on the tongue.

    It is important not to consume biotin alone, but to have a full range of vitamins and minerals in the diet.For more detailed advice, you can contact the manager on the Biotus website.

    What benefits does it bring to the body?

    Lack of biotin in the body leads to unpleasant consequences, these are:

    • Dullness and hair loss
    • Unhealthy skin color and dry, flaky skin
    • Brittle nails, slow growth
    • Loss of appetite
    • Feeling nauseous
    • Unhealthy tongue color
    • Muscle weakness

    It is most beneficial for hair growth, but there are still positive effects:

    • Eliminates inflammatory processes
    • Plays a huge role in the assimilation of amino acids and protein
    • Normalizes fatty acid metabolism, exerting a lipotropic effect
    • Provides muscle energy

    Is there any harm from taking biotin?

    Foods and supplements with a high biotin content are not contraindicated, but before taking it, be sure to consult a doctor, because all people are different and each has individual characteristics.If you take more biotin than normal, a rash may appear. Although the excess is excreted in the urine, such phenomena are possible, then consult a doctor.

    How to take biotin?

    The need for biotin is often observed in pregnant women, especially with toxicosis, when it is not possible to consume the required amount of food. People with colon lesions may also be deficient in biotin.

    Biotin is found in foods, but in small amounts to get your daily value, choose foods that contain more vitamin B7.In order to make it easier to take, you can take the supplement in the form of tablets already at the required dosage. Whichever way of use you choose (in the form of food or in the form of a supplement), make sure that biotin enters the body every day.

    Since biotin has a cumulative effect, take it every day, then you will notice improvements in 60-90 days after you start taking it. The longer the better.

    How much do you need and how to drink?

    Biotin Dosage Recommendations:

    The intake of biotin is 30-50 mcg per day.This is the optimal dosage per day. For medicinal purposes, a larger amount should be taken as directed by the attending physician.

    If there is a need for biotin for a child, then there are recommended dosages depending on age: up to 3 years of age, you can 10-20 mcg, up to 6 years – 25 mcg, up to 10 years – 30 mcg.

    Pregnant and lactating women need an increased dose of biotin, but you should consult your doctor before taking it.

    What foods contain biotin?

    Biotin is found in many foods, and usually there are no problems with its deficiency.

    Here are some of the foods that contain more of this vitamin.

    • Chicken liver – 170 μg
    • Egg yolk – 56 mcg
    • Beef / Pig Liver – 40 μg
    • Oatmeal, peas – 15-20 μg
    • Rice, wheat porridge – 10-12 μg
    • Cottage cheese, soft cheese, salmon – 5.1-8.4 μg

    Heat treatment can reduce biotin volume, so choose foods that have been minimally heat treated.

I will take a jar until the end of 1 tablet a day.(the only thing is that somewhere there are 10 tablets in a package less than the specified one)

    Wonderful Biotin! Wonderful Biotin! I ordered myself and my friends. The reception fell on the fall of the hair. Hair stopped falling out altogether (if a few fell out, then everything is within the normal range and it should be so) It is 300 mcg that is the recommended daily rate.

    Score: ⭐⭐⭐⭐⭐

    good I bought Biotin hoping to make my hair stronger.The tablets are very small and easy to swallow. It is not clear why such a bank is big for them, if they take up less than half of the space. I take 1 tablet a day and believe in its usefulness.

    result after a month’s course! After a month of use (now 2 months have passed), I noticed a clear improvement: nails grow quickly, hair falls less, but the MAIN THIS IS EYELASHES !!!!! The branches are thick and long! Better than after using known products that stimulate the growth of eyelashes.I strongly advise those with hair loss to add the product to the complex treatment of hair loss

    The miracle did not happen They must be doing something, just too imperceptibly. Biotin alone did not cope with hair loss. I drank biotin Natrol 10,000, switched to this one. I wanted a miracle – the miracle did not happen. I do not see any difference, the effect is also. Now I take vitamins, including group B, minerals and iron (confirmed by analyzes of railway anemia) and this biotin.Hair loss is, as a rule, a complex of reasons (in my case, I see it like this: gastrointestinal tract, stress, IDA). If after 7 months of taking biotin nothing changes (that is how much I have in stock), I will not order any more; I will be content with the amount included in the capsule of B vitamins (usually 1000-1000mcg). Thank you for thank you!

    I saw through the biotin. If you have real hair loss problems, it certainly won’t help, but as a support, nutrition is a good thing! I drank one jar, I did not notice any positive effects, but I did not take anything else, perhaps in conjunction with other products, there would be a different result!

    Score: ⭐⭐⭐⭐⭐

    The result is I took it from baldness, the effect, of course, is, the hair became thicker, it falls out less often, visually in a month some positive change is barely noticeable, but globally it does not solve the problem.I will definitely continue the reception.

    Side effects – acne I have been drinking biotin in a mandatory complex for the second year. I tried three manufacturers, but only from this biotin on the third day of taking, huge subcutaneous acne appeared. I canceled it right away, after a few days everything returned to normal. I saw a similar review, but did not pay attention.Now I’m sorry. Anyone who faces a similar problem – choose another firm’s biotin.

    Excellent product Biotin is simply excellent, incredibly satisfied with the effect, I really feel how the missing reserves in the body are replenished and slowly, with each course, as if layer by layer, everything that was destroyed long ago is being restored.Indeed, I advise everyone, you will not regret it.

    I like So far I take biotin every day, in the evening at dinner, but I wait for my order with pantothenic acid (B5) to arrive and alternate them every other day, because they are not compatible, and when taking biotin in large dosages, the content drops in the body of vitamin B5.I drink biotin in combination with other vitamins and minerals, I haven’t noticed anything negative yet, hair grows well, nails too)) I have no doubt that it works, all the same the dosage is decent!)

    Will not buy again. Hair really stopped falling out at the time of admission. I also noticed that when taken, the hair gets greasy with terrible force, at the end of the second day the hair looks greasy as if it had not been washed for about a week (no exaggeration).at the end of the reception, the hair loss continued

    Truly strengthens your nails! I am a skeptic, but my nails have always been thin and exfoliated, so for the sake of testing I bought this biotin. It is very convenient to take, tiny tablets dissolve in the mouth in seconds, they do not have much taste. After about a month of taking, I realized that my nails had become hard and firm, very unusual sensation, pronounced.If earlier nails, even short ones, were easily bent and regularly cracked, now this is not even close. Surprised, I will continue to drink.

    Simple, Clean and Effective Biotin Everything is exactly as the manufacturer says in its motto: simplicity, purity and efficiency. One hundred small neat “stumps”, dissolving very quickly under the tongue, neutral taste, no preservatives. The dosage is one microlingual tablet per day.Very comfortably. In my case, I note a positive strengthening effect on hair and nails. The only caveat: these tablets contain lactose as an auxiliary component, so people with its intolerance are better off choosing a different form of biotin. All beauty and health!

    Ordered a second can. After 2 births I got a small bald patch right in the most prominent place. And whatever I did – masks, vitamins, darsonval and a bunch of everything. I chose this jar because of the successful composition, plus I also saw zinc separately in addition. As a result, after 2-3 months after the course of these pills, fluff appeared and now, after 6 months, my bald patch is overgrown. The rest of the hair falls out in the same way as before – standard hair loss.Nails, yes, for a while (several months) became better. ordered more, to strengthen the result 🙂

    Possibly the reason is not in biotin I drank the jar, while I can’t talk about the results, they write everywhere that don’t expect the result right away. The presence of lutein in the composition is encouraging, it is good for the eyes. I am taking anticonvulsants, and they impair the absorption of biotin.But probably not quite they absorb it))) I add to the review after a while, I did not notice any effect, the hair continued to crumble !! Perhaps this is not the reason, I bought a hair complex of the same company, so they helped me, two weeks later !! I hope after the cancellation the hair loss will not resume)))
